以下是原文作者的评论～
老农修正:保存cookie的时候,原先是session的值,放在数据库里面,取出,写入默认值,这样一般用不到,通用的为:
sub SaveCookie_tvillage()
Response.Cookies(“tvillage”)(“User”)=user
Response.Cookies(“tvillage”)(“Password”) = PassWord
Response.Cookies(“tvillage”)(“jibie”) = jibie
Response.Cookies(“tvillage”)(“CookieDate”) = CookieDate
select case CookieDate
case 0
””not save
case 1
Response.Cookies(“tvillage”).Expires=Date+1
case 2
Response.Cookies(“tvillage”).Expires=Date+31
case 3
Response.Cookies(“tvillage”).Expires=Date+365
end select
end sub
